The answer to “Sometimes you need to integrate only the “tail” of a Gaussian function, from some large x up to infinity: Evaluate this integral approximately as follows. First, change variables to s = t2, to obtain a simple exponential times something proportional to s?1/2. The integral is dominated by the region near its lower limit, so it makes sense to expand s?1/2” is broken down into a number of easy to follow steps, and 60 words.
